Can you please tell me if ii is necessary to remain on a beta blocker if TSH is 0 but free t4 is normal? The TSH has been 0 for 1.5 years despite rx with Tapazole for a year. I have no symptoms but have occasional episodes of atrial tachycardia ( last holter showed 22 short runs with longest run at 22 beats and occasional sinus tachycardia. We are not certain if the tachy is r/t thyroid or not as had these rhythms when had a nl TSH a couple years ago. An ablation was done a few years ago for 50,000 PVC's and v tachycardia. No diabetes, bp 126/82 and occasionally a little higher. I really dislike taking beta blockers (very tired) and wondering if they could be stopped. Echo is normal. Thank you so much.
Dear mitzi 2987,
Thank you for your query.
I have gone through all the details that you have given.
At the outset, let me reassure you that you don't need to be so anxious. Many of the symptoms that you have described can be attributed to the facts that you have just had a baby, you have lost a lot of blood, and your hemoglobin is still not normal. Some of the symptoms may also be due to fluctuations in BP and the BP medicines may also be partly responsible. In my opinion, your symptoms should resolve once the anemia is completely corrected and your BP is adequately controlled with appropriate medicines.
You should also ensure that you always remain well hydrated. Reduced fluid volume can cause marked changes in your heart rate when you stand up from a lying down position and also giddiness due to drop in BP at that time.
A heart rate of 44 during sleep is perfectly acceptable as long as the rhythm is a normal sinus rhythm. There is no need to be anxious on that count. The increase in heart rate with standing and a reduction with sitting can be explained by anemia, dehydration and possibly the effect of certain types of BP medicines. This can be completely corrected.
Since you are on Warfarin (which is an oral anti-coagulant), you should ensure that the dosage is adjusted once in 3 to 4 weeks to maintain an INR value between 2 and 3. Too less would mean chances of recurrence of DVT while too high would mean risk of bleeding and worsening of Anemia.
I would be in a position to provide more precise opinion if you could share the following details:
1) The names and the doses of the BP medicines that you are taking?
2) What are your ECG and echo findings?
3) Has the DVT completely resolved?
4) Have you checked the INR (International Normalized ratio) value and Prothrombin time? Is the INR value between 2 and 3?
Hope that this information helps and hope that you will get better soon. Do get back to if you have further queries.
